Active Recombinant Human IL1R1, His tagged

• Cat.No.: IL1R1-772H
• Product Overview: Recombinant Human IL1R1 extracellular domain (NP_000868.1) (Met 1-Thr 332), fused with a fused polyhistidine tag at C-terminus, was produced in Human Cell.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: Met 1-Thr 332
• Form: Lyophilized from sterile 50 mM Tris, pH 8.0.
  Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: 1. Measured by its ability to bind human IL1-beta in a functional ELISA.
  2. Measured by its ability to inhibit Interferon gamma secretion by human natural killer lymphoma NK-92 cells in the presence of 500 pg/mL IL1b. The EC50 for this effect is typically 40-200 ng/mL.
• Molecular Mass: The soluble form of recombinant human IL1R1 consists of 326 amino acids after removal of the signal peptide and has a predicted molecular mass of 37.6 kDa. In SDS-PAGE under reducing conditions, it migrates with an apparent molecular mass of 51-57 kDa due to glycosylation.
• Endotoxin: < 1.0 EU per μg protein as determined by the LAL method.
• Purity: > 97 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
  Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
